Service Overview

Our tank testing services can help to ensure your critical infrastructure remains servicable and compliant in relation to current Environment Agency standards.

It is important to test your tanks for several reasons. Firstly, due to modern refining techniques, fuel is now injected with more and more additives.  As a result, these additives can hasten the corrosion and degradation of your fuel storage tanks. Secondly, a high sludge content caused by rust, dirt and water in your fuel can lead to a blockage and further damage to your systems.  Regular tank testing can decrease your risk of;

  • A system failure, 
  • Tank and pipework damage
  • A serious leak – causing ground or watercourse contamination
  • A breech of your insurance contract resulting in a refusal to pay-out

Regular testing, inspecting and sampling is an essential maintenance and preventative measure that can protect your assets and save you money.


Our tank testing service will be carried out by our OFTEC registered engineers. At JWH Tanks, we use precision testing equipment accompanied by safe and non-intrusive procedures.  Our tank testing services include;

  • Precision tank testing
  • Fuel line pressure testing
  • Vent line pressure testing
  • NDT Testing
  • Internal visual inspections
  • OFTEC Inspections

As part of the tank testing process, our clients are given a detailed but easy to interpret report. The report shows our findings and any recommended remedial actions. Regular tank testing of your fuel storage should minimise the risk of any major problems occurring. If the test highlights a problem, our specialists will be able to advise you on, and carry out, any necessary corrective actions. Remedial actions may include;

  • Tank cleaning
  • Internal tank inspection
  • Installation of a temporary tank
  • Welding repairs
  • Installation of new tanks
  • Replacement of lines
As well as all of the above, our in-house experts can offer bespoke solutions which are tailored to your individual needs.

For your peace of mind, we are accredited under the SafeContractor, CHAS and Constructionline schemes for safe systems in Procurement.
